FREEWAREFILES EDITOR'S REVIEW

 Reviewed on August 05, 2014

There are times when ordinary calculators do not suffice to calculate some complex mathematical problems, even the scientific ones. If you are dealing with unconventional functions, then you need something more, which is where Kalkules comes in handy. The free scientific calculator comes with a wide range of options and capabilities.

Features:

  • Calculating with modulo, complex and real numbers
  • Evaluating complex expressions
  • Calculating in decimal, hexadecimal, binary and octal number systems
  • Function graphs
  • Unit conversion
  • Expression libraries
  • Calculating with fractions and polynomials
  • Making basic combinatorial and statistical expressions

Using Kalkules

The installation process was smooth, and the calculator launched fast, displaying buttons with various mathematical functions. The display was divided into three sections: expressions to calculate appeared on the upper left side and the results appeared on the right side while the lower left section displayed the value we saved in memory.

The buttons on the top of the display were divided into four sections for selecting the set of numbers, angle unit, number system and shrink option. Just below the display were buttons for differentiating functions, calculating series summations and drawing graphs of the entered functions among others. Other things we could choose below the displays included hyperbolic functions, fractions and the number of desired decimal places.

Several options made it easier and more convenient to use the calculator. For example, checking the box to automatically close parentheses enabled the program to automatically close all parentheses left unclosed before making calculations. We could also choose the items we wanted to save for restoration when we launched the calculator next time.

The calculator did not limit us on the number of brackets we could use on a mathematical expression. We found it convenient to add spaces when handling complex expressions, which the program ignored during calculations. The expression browser allowed us to store expressions and formulas we often used, including relevant descriptions.

We could use the free scientific calculator to solve complex expressions with constants, variables and parentheses and then display the results in various formats. This means we could also use the program to convert from one number format to another. We could also convert angles easily.

Conclusion

Kalkules is a versatile and free scientific calculator that allows people to solve unconventional expressions that ordinary calculators cannot handle. Although the program is relatively easy to use, it is clearly geared towards people with some level of math skill to take advantage of its full potential.

Software Product Description

Kalkules is an universal scientific freeware calculator, which can be used particularly by high school or university students. It also offers a wide range of tools.

Features:

  • evaluating complex expressions with parenthesis, variables, constants and functions
  • calculating with real, complex, and modulo numbers
  • calculating in four number systems: binary, octal, decimal, hexadecimal
  • wide range of arithmetic goniometric and hyperbolic functions
  • function graphs
  • function differentiation
  • calculating with polynomials and fractions
  • unit conversion
  • basic statistical and combinatorial calculations
  • expression libraries
  • evaluation history
  • and much more...

What's New in version 1.9.6.25:

Improvements:

  • Added Turkish translation
  • Added function exp(x) (equivalent to expression $e^x)
  • Added logical binary operators and, or, xor
  • Added these new prefix values which can be used in expression: Zetta, Yotta, Zepto, Yocto

Fixes:

  • Setting 'Insert last result (ANS) and operator' didn't work with some operations
  • Multi character operators could get mixed up with operands in HEX mode
  • When using several multi character operators without parentheses, all operators except the first one got confused for a variable. For instance: 10 div 2 mod 2
  • Using a specific combination of variable names in the expression caused a calculation error. For instance: a*va/2
  • Program crashed when the user tried to insert a prefix value

Pros: None

Cons: None

Other Thoughts: As they say, Italians do it better (besides French of course!)
Seriously (but I WAS serious), this calculator is ingenious, allows complex calculations with ease, follows natural thinking, smart.
